Title: Automatic prodn. of plastic bags - machine is operated by computer-controlled system in which each function is performed by servo-motor receiving set number of impulses
Inventor: SCHNEIDER JAKOB
IPC: B31B19/10
Filed: 1990-10-26
Abstract: Plastic bags are produced in an automatic machine which has a feed for double-layer plastic film with at least one pair of traction rollers, a welding and cutting device, and separate servo-motors for the feed, welder/cutter, and a computer control. The web of film is drawn off its reel by the traction rollers at adjustable intervals in the feed lengths; it is made into the bags at the welding/cutting station and picked off by a device upon each cycle using control impulses. These are passed to the servo-motors so that one transporting step through one feed length is made between a zero point and Y impulses. Equally the welding/cutting device is activated in an interval between y and z impulses. The speed (n) of revolution of the feed drive is set by the computer control according to function related to the control impulses; the speed function is set according to the computer control and an average ((DM) calculated from the feed length and number of cycles plus also a max. speed (mMax) set by the permissible power of the servo-motor. The speed function for one band given by nM is upto 0.5 x nMax consists of a function which begins at zero impulses and rises linearly and an end function which falls linearly after y impulses. The max. function is matched according to the average speed nM; the speed control function for the band nM is more than 0.5 x nMax consists of a function section which begins at zero impulses and rises linearly to a limiting value for the max. speed nMax, it consists also of a function section which ends after y impulses and falls linearly from the limiting value to zero, and of another function section which joins the two linear sections in a saddle shape and which matches the width of intervals of the saddle-shaped section according to the average speed nM. ADVANTAGE - The system minimises the energy consumed of the feed and it makes the power consumption more uniform.

Patent DE-4207595-A1 (DE)
Inventor: SCHLANG MARTIN F DR ING
IPC: G06N3/063
Filed: 1992-03-10
Abstract: A preclassification process of high-dimensional characteristic vectors for signal processing purposes is disclosed. In a first data reduction step, the dimensions of the characteristic vectors are reduced, using a neural algorithm that allows particularly quick learning the weighting values to be achieved. In a second step of the process, the low-dimensional characteristic vectors are grouped into individual clusters. Thanks to a special fusion procedure of the individual clusters, the number of required spacing calculations is minimal. This process is particularly suitable for pre-classifying biomedical data.
